<div dir="ltr">This guy might be misled by another guy. that
another guy in a video (sorry I can't remember the
address), make a glass TLUD stove, and showed that the
smoke (gas) move out from primary air hole into the layer
between inner and out cylinder, then upward and then
re-enter the inner cylinder. that help him to explain why
the flame jet out from the secondary air holes.

<div>His experiment did show some smoke move this way
somehow. but it is not the mainstream. </div>

Comment by PSA: Impressive. Very much a demonstration that
raises questions. Downward flows. But mot totally downward
(unknown percentage, to be studied)..<br>
<br>
And then at the end, there is a "click here" box to go to further
work. <br>
<br>
Part B. <br>
<br>
That box takes you to <br>

<br>
Same fellow. and showing clearly UPdraft. Side by side
comparisons. Well worth watching. <br>
<br>
That is dated 2015. I hope that somebody will delve into this
further. There is still a great deal of TLUD science to be
researched.<br>
<br>
This all is (in my opinion) support for thinking the micro-gasifier
stoves (ACS for Advanced Cookstoves) will continue to get better and
better, further distancing them out ahead of the stick-burner ICS
(Improved or Inadequate Cookstoves). <br>

I stumbled onto this video by accident. He is
instructing (64,000 views) that the air in the
fuel chamber of a woodgas stove (same drawings as
for a TLUD) are moving DOWNWARD.<br>

Totally bogus.<br>
<br>
I would not even mention it to the Stoves Listserv
except to express my disgust and to point how what
is creeping into information flows about stoves.<br>
<br>
Might be a nice challenge for students to try to
PROVE the direction of the air flows in TLUD
stoves. Such as an increase in temperature in
the bottom few cm of the fuel if the hot gases
were pulled downward. Of detecting combustible
gases in the gap between the fuel cylinder and the
outer cylinder.<br>
